my CEL just came back on, after about 500 miles, i know that is where the computer begins to gather positive data from the emissions system, however, i do not have a cat, so i made myself a rear o2 bypass/simulator using the DIY instructions on tuners... well, obviously, that didn't work... and i need a state inspection (OBDII)... any ideas? (i dont want to buy a cat) heard of this little trick of using "spark plug non fouler" and thread the o2 sencor into that...
